Power outages in Potomac, MD can last hours or days. A professionally installed standby generator with automatic transfer switch keeps your home or business powered automatically, with no manual setup, no extension cords, and no disruption. REOC Electrical Solutions installs whole-home and commercial generator systems throughout Potomac, MD with full permitting and certified commissioning.
There are two main categories of backup power for Potomac, MD homes: standby generators and portable generators. Each serves a different purpose and requires different installation expertise. Understanding the difference is essential to choosing the right solution for your property and budget.
A standby generator is a permanently installed unit mounted on a concrete pad outside your Potomac, MD home, connected to your electrical panel through an automatic transfer switch (ATS) and fueled by natural gas or propane. When the grid loses power, the ATS detects the outage within seconds and automatically starts the generator, restoring power to some or all circuits in your home without any action from you. When utility power returns, the ATS transfers back automatically and the generator shuts down. Standby generators are the most complete power backup solution available for Potomac, MD properties.
Portable generators produce power but require manual setup, running extension cords or connecting to the home's circuits through a manual transfer switch. REOC installs manual transfer switches and inlet boxes for portable generators throughout Potomac, MD, allowing safe connection of a portable unit to selected circuits without the risk of backfeed to the utility grid. A portable generator connected without a proper transfer switch is a serious electrocution risk for utility workers and is illegal in Potomac, MD and most jurisdictions.
If your Potomac, MD home is connected to natural gas service, a gas-fueled standby generator is typically the most convenient option since it draws from an uninterrupted supply line and never requires refueling. Propane is an equally reliable alternative for properties without natural gas access, provided the storage tank is sized appropriately for the expected outage duration. REOC evaluates your property's fuel infrastructure during the initial assessment and helps you select the fuel type that best fits your location, usage expectations, and long-term cost profile.
Selecting the right generator size is one of the most consequential decisions in the entire process. An undersized unit will overload and shut down when it matters most. An oversized unit wastes fuel and accelerates engine wear through excessive light-load operation. REOC performs a formal load calculation for every Potomac, MD installation, accounting for starting load requirements of motor-driven equipment like HVAC compressors, which draw significantly more power at startup than during steady operation.
From whole-home standby systems to portable generator hookups, REOC covers every category of backup power installation for residential and commercial properties throughout Potomac, MD.
Complete installation of Generac, Kohler, Briggs & Stratton, or Cummins standby generators with automatic transfer switch, powering your entire Potomac, MD home automatically during outages. Includes concrete pad coordination, fuel line connection, ATS installation, and full system commissioning. Your home powers on within seconds of an outage, with no input required from you.
A smaller standby or portable generator connected to a critical-load panel powering only essential circuits, HVAC, refrigerator, lights, and key outlets, at a lower cost than whole-home coverage for Potomac, MD homes. An ideal solution for homeowners who want reliable backup for the most important systems without the full investment of a whole-home system.
ATS installation is the key electrical component of any standby generator system, connecting the generator to your Potomac, MD home's panel and automating the transition between utility and generator power. REOC installs ATS units from all major manufacturers and configures them for your specific panel layout, circuit priorities, and generator make and model.
Safe connection infrastructure for portable generator users in Potomac, MD, allowing proper connection to selected circuits without dangerous backfeed through a code-compliant inlet box and manual transfer switch. A much safer and more practical arrangement than extension cords, and legally required in most jurisdictions when connecting a portable generator to your home's wiring.
Larger standby generator systems for Potomac, MD commercial properties, including offices, retail spaces, data centers, medical facilities, and restaurants, sized for critical load requirements and installed with commercial-grade ATS. We work with your facility manager or electrician of record to ensure the installation integrates cleanly with your existing electrical infrastructure and meets all local code requirements.
Upgrading an existing portable generator connection from extension cords to a proper transfer switch system, or upgrading an older manual ATS to a modern automatic model for your Potomac, MD property. If you already own a generator but have been operating it unsafely or inconveniently, this service brings your setup into full code compliance with minimal disruption.
Every generator installation follows a structured six-step process designed to eliminate surprises, ensure code compliance, and deliver a system that performs reliably when you need it most.
We calculate your Potomac, MD property's critical load requirements, including HVAC, essential appliances, medical equipment, and lighting, to determine the correct generator size. An oversized generator wastes fuel and accelerates engine wear; an undersized one fails to protect what matters. Our load calculations account for motor starting loads, which are significantly higher than running loads for compressors and pumps.
We identify the optimal generator placement meeting minimum clearance requirements from windows, doors, and gas meters, with appropriate pad sizing and fuel line routing, before committing to any location. Proper placement also considers noise impact on neighboring properties and accessibility for annual maintenance. We document the planned location in writing before any work begins.
Generator installation in Potomac, MD requires electrical permits and in some cases utility notification. We handle all permit applications and coordinate with gas utilities for natural gas connections as needed. Our familiarity with Potomac, MD's building department processes means permit approvals move as quickly as possible with no back-and-forth delays from incomplete applications.
We install or coordinate the concrete pad, deliver and place the generator unit, and handle all physical installation including vibration isolation pads and weatherproof junction connections. The pad is sized and reinforced to the generator manufacturer's specifications and positioned to allow easy access for annual service visits. All outdoor electrical enclosures are rated for exterior use and installed to prevent water intrusion.
The ATS is installed at or near your Potomac, MD home's main panel, all electrical connections are made to code, and the generator's exercise cycle and auto-start sequence are configured and tested. We verify that the ATS correctly prioritizes circuits during a partial-load scenario and that generator output voltage and frequency are within specification before transferring any load.
We simulate a power outage, verify automatic transfer within the manufacturer's specification, run the generator under load, and walk you through maintenance requirements before providing inspection documentation and warranty registration. You receive a complete commissioning report, permit and inspection records, and the manufacturer's warranty documentation as part of your project close-out package.
Generator installation is a complex multi-trade project involving electrical, gas, concrete, and utility coordination. Experience and thoroughness matter far more than price alone.
We pull every required permit, attend every inspection, and provide the complete documentation package at project close-out. No shortcuts, no unpermitted work, no future liability for you.
We install Generac, Kohler, Briggs & Stratton, Cummins, and Champion. We recommend the unit that best fits your requirements, not the one with the highest margin for us.
Your written estimate details every cost: generator unit, ATS, pad, labor, fuel line work, permits, and utility fees. The estimate is your final price unless genuinely unforeseen conditions arise, and those are discussed with you before any additional work proceeds.
